A research project by NASA is investigating the use of Ethereum-based smart contracts to help spacecraft ‘think on their own’ and avoid collisions by detecting and avoiding floating space debris. In addition to automating spacecraft maneuvers, NASA hopes to develop a decentralized, secure, and cognitive networking and computing infrastructure for deep space exploration, leveraging blockchain technology’s consensus protocols to improve infrastructure resilience.
